XRP6275 3A Ultra Low Dropout Voltage Regulator January 2015 Rev. 2.0.0 GENERAL DESCRIPTION FEATURES The XRP6275 is an ultra a low dropout voltage regulator capable of delivering 3A output currents. It is unique in the industry in being able to operate from a single supply rail of 1.045V to 2.625V without the need for a noise generating charge pump. • 3A Output Current With its ultra low dropout voltage of 138 138mV at full load guaranteed over temperature, the XRP6275 achieves conversions onversions previously unavailable. The output voltage can be set as low as 0.6V with ±0.5% accuracy making the XRP6275 perfectly suited for powering low voltage devices such as FPGAs, DSPs, ASICs, and other SOCs. Built-in in current limit, reverse bias and thermal protection ensures safe operation under abnormal operating conditions. An enable function, soft start and Power Good flag complete the feature set. The XRP6275 is offered in RoHS compliant, “green”/halogen free 10-pin pin 3x3mm DFN package. • 1.045V to 2.625V V Single Input Voltage − Adjustable Output Voltage ≥0.6V − ±0.5 Output Voltage Accuracy • Ultra Low Dropout Voltage − 138mV mV Max over temp @ 3A 3 − 74mV Max over temp @ 2A • Power Good Flag • Enable & Soft Start • Current Limit and Thermal Protection • Reverse Bias Protection • RoHS compliant “Green”/Halogen Free − 10-pin pin 3mm x 3mm DFN APPLICATIONS • Point of Load Conversion • Microprocessors, DSPs, FPGAs Supplies • Networking & Telecom Equipment • Switching Supplies Post Regulation TYPICAL APPLICATION DIAGRAM XRP6275 Fig. 1: XRP6275 Application Diagram Exar Corporation 48720 Kato Road, Fremont CA 94538, USA www.exar.com Tel. +1 510 668-7000 – Fax. +1 510 668-7001 668 XRP6275 3A Ultra Low Dropout Voltage Regulator ABSOLUTE MAXIMUM RATINGS INGS OPERATING RATINGS These are stress ratings only and functional operation of the device at these ratings or above any other of those indicated in the operation sections of the specifications below is not implied.
